just wondering anyone has done this type of thing before and replaced standard fluro tubes with led fittings?
Yes, its quite common. The old vanda light is a very common fitting, being a direct replacement but in an LED version is an attractive option as the foot print, fixing hole locations and cable entries are all the same making for a quick simple cost effective change over.
thoughts appreciated.
I could not think of a worse fitting that I would want in an out door entertaining area but I can understand why you would go the direct replacement option as per my above comment.
I would personally go for a look at some lighting shops and pick a nicer fitting particularly if its a covered area and try to go for something dimmable.
